Mt.Vesuvius is an active Volcano located on the west coast of Italy. Around 79 A.D this volcano erupted, and encased Pompeii, and Herculaneum in volcanic ash. Why this happened, how it damaged the environment, how human lives have been impacted and, how we prepared and recovered from the natural disaster will be covered. Mt.Vesuvius is still an important natural disaster. First is how and why Mt.Vesuvius erupted in 79 A.D. The earth is split up into plates, and Mt.Vesuvius sits on the Campanian Volcanic Arc. The arc is on the African plate being subducted by the Eurasian plate. Mt.Vesuvius is on a tear in the African plate which allows heat to flow upwards. This causes a buildup of molten rock, and a violent eruption is the result. There was also a few a earthquakes weeks before the the eruption occurred. The second is how this damaged the environment. This volcanic explosion caused volcanic ash to coat the entire city of Pompeii causing everything to be “frozen” or more accurately cemented into history. The city of Herculaneum was also encased in Volcanic ash. Mt.Vesuvius is classified as a stratovolcano, which is explosions and pyroclastic flows. Things were frozen so quickly that it provides an accurate display of what life, and the environment. This shows how people lived, and what their environment was like. The diets of the time can still be observed since what they ate was also cemented, and since the people were cemented their diets were preserved and we can know what it is. The third is how human lives were affected. Life had ended in a flash, and so did everything in the area. The entire environment had been destroyed which prevented future life from being able to grow, or flourish for years. All organic life had either been destroyed or encased and cemented in time. An area that once had flourished and been prosperous, had been destroyed in an instance. The eruption had covered both of the city’s in volcanic ash within an hour. The citizens from the city of Herculaneum fled to Pompeii, but were unable to escape the encasement. The fourth point is how the citizens prepared for this. The fact is that they did not. Even though the volcano had been active city’s were not evacuated. The only reason the cities were built near the volcano was because they were near or were port cities. This meant that it was convenient for the times as ports were one of the most important parts of the cities. Before the explosion happened the volcano was showing signs of eruption which was documented by Pliny the younger. He had observed that the volcano had been smoking, and the smoke could be seen from far away. Even when volcanic ash started falling most of the population still did not evacuate the cities.When the eruption happened people looked for shelter underneath houses or market stalls, but were sadly unable to escape the magma, and flying rocks. The final point is what we do know to prevent future accidents. Firstly, we now have more knowledge about the volcano and how the plates underneath it are moving. We can also learn from the citizens of the two cities, because that time was cemented, and preserved, we can study about what their lives, and environment was like. There was also more activity during World War Two. Soldiers had to wear metal hats, and protective clothing to shield themselves from volcanic ash. In conclusion, we have learned a lot about Mt.Vesuvius. Why this happened, how it damaged the environment, how human lives have been impacted and, how we prepared and recovered from the natural disaster has been covered. The eruption of Mt.Vesuvius in 79 A.D was a tragic natural disaster.
